The flannel moths or crinkled flannel moths (scientific name Megalopygidae) are a family of insects. They occur in North America (11 species) and the New World tropics.

These moths occur in North America and the New World tropics.^{[citation needed]}

Adult flannel moths are stout-bodied, and very hairy. Females have thin antennae while males' are feather-like. Larvae are called puss caterpillars and, with their long hairs, resemble cotton balls. They are eaten by green lacewing insects and the Anolis lizards. They have venomous spines that can cause a painful sting and inflammation lasting for several days. In some cases, the sting may cause headache, nausea, and shock-like symptoms. Perhaps the most notorious for stinging is the caterpillar of Megalopyge opercularis. Caterpillars have seven pairs of prolegs, while other Lepidopterae have five or fewer pairs. They feed on a wide variety of deciduous trees and shrubs.^[1]
